P r o d u c t S p e c i f i c a t i o n s Thermo Scientific Sarasota RTR900 Instrument Retra ctor for use with the Ther mo Scientif ic Sara sota ID900 Ga s Dens ity Me ter The Thermo Scientific Sarasota RTR900 instrument retractor enables the safe insertion or removal of a Thermo Scientific Sarasota ID900 gas density meter from a pipeline or tank without the need to shutdown the process. It is suitable for use in high pressure applications up to the maximum working pressure of the Sarasota ID900 of 150 bar (2175 psi), or flange rating. Mounted on a standard ball or gate isolation valve, the Sarasota RTR900 is secured to the system pipeline with a flange to suit customer requirements. Designed to accommodate the Sarasota ID900 with a 1000 mm (39.4 in) stem within the retrac tor shaft, the Sarasota RTR900 also comprises a handwheel, sea l housing and ve nt valve. The Sarasota ID900 is inserted or removed from the line or vessel by the rotation of the handwheel. After retracting the instrument from the line, a simple venting procedure ensures that the meter is fully isolated and depressurized before removal. The option of a second vent valve allows the density meter to be isolated in the retractor and the isolated volume to be evacuated or purged, enabling the introduction of a sample gas for online validation of the density meter’s calibration. Complete retraction requires an unobstructed headroom of 1400 mm (55 in). A simple mecha nical interlock b etween the vent valve and the retractor closure system minimizes the likelihood of the retractor seal housing being opened while the retractor is still pressurized. Routine maintenance to the Sarasota RTR900 is minimal and can usually coincide with the routine maintenance of the Sarasota ID900 and other line instruments to maximize uptime. The Thermo Scientific Sarasota RTR900 instrument retractor allows the Thermo Scientific Sarasota ID900 gas density meter to be installed directly into the pipeline or tank under operational conditions. The Sarasota RTR900 enables the safe insertion and removal of the Sarasota ID900 without the need to isolate or depress urize the pipeline or process, avoiding the inconvenience and costs associated with downtime while contributing to plant safety.
